To promote its new products competing against Google (News - Alert), Microsoft’s strategy has been to thrash the rival using YouTube videos and ads on other mediums. In the past, this strategy was used to promote Web search engine Bing against Google and e-mail service Outlook.com against Google’s Gmail. The software giant has now adopted the same strategy to promote Windows Phone apps against Google apps.

In the latest campaign against Google ads, the software giant has been promoting ads called Scroogled, which depicts Google as a fraudulent company that is interested only in increasing profits and power rather than protecting people's privacy and providing unbiased search results. In this ad, which went online on TV and in print, Microsoft (News - Alert) is denigrating the search engine giant for sharing some of the personal information that it gathered on people who bought applications designed to run on Android (News - Alert) powered smartphones and tablets reported Huffington Post.

While thrashing Google, the Microsoft ad claims that it can offer a better alternative that does not do nefarious things. The report shows that Microsoft has been running this anti-Google campaign for some time now.

All Things D reports that last week, soon after Google’s I/O developer conference, the search engine giant’s YouTube (News - Alert) sent Microsoft a cease and desist letter demanding that Redmond, Wash.-based software company must shut down a YouTube app it had built for its Windows Phone.

As per the report, Google’s issue with the Microsoft app is that it is on YouTube’s public data feed and violates the video site’s terms of service. Primarily, it strips out YouTube’s ads, wrote freelance reporter Peter Kafka. The report says that Windows Phone users can still watch the YouTube videos via their Web browser, “but the experience isn’t as slick as a dedicated app.”

Findings further indicate that Microsoft should know better how to use YouTube as its Xbox app was jointly developed with Google. Also, Google CEO Larry Page (News - Alert) closed the Google event by saying “he’s got nothing but love for everyone, everywhere — even if they’re building rival technologies.”
